" f The device-is shown. si pported wall,

portion lot a yibratorbomwhich has trans? ""verselyextending' bores-2' and"3,"formed' therein, and the d'evicepomprise's' a base plate.- 4, having annular flange 1 juxta sulating fmaterial, and certain other elements to be, subsequently described. The baseplatehas apertures 8 and 9 formed thereimtobe alined with apertures 2 and 3,

frespectively,10f support 1, the aperture 8 t beingsc'rew, threaded The dial members 5 "and ,6 have concentrically disposed apertures 5f, andv 6", respectively, which are al-ined with apertures 9 and 2, and through which extends a bolt 11 havin a head 12, at the end adjacent the dial mem er 6, a-spring washer; 13 having .fingers 14, being interposed between the head 12 and the dial memberlfl." On the other end of bolt 11 is turned a lock nut 15, which draws the same to hold all" of the dial members in close contact with .jea'ch other. and base 4, but ermitting rotation thereof through the s ightly yieldable washer 13, .By means of washer 16, rigid with theiwall. portion 1, embracing the bolt l l next. adjacent the nut 15, I electrically connect said bolt with a conductor 17, which may be operatively connected with one pole of theelectric generator, (not shown in the drawing), ascrew118, carried by the washer 1.6,- securely holding the conductor in place. 'Theldial member 6 has embedded therein land exposed atits face, next adjacent ,to "washer 13 and contacting with the fingers 14: thereof, a conducting ring 19 provided with a screw 20 passing to the periphery of the dial member and flushtherewith.

f Aline d to be contacted with screw 20 is a transversely 3 extending conducting mechanism, 21 carried by flange-5' and substantiallyiflush therewith at both the internal and external peripheries. The flange 41 carlies a conductor 22 alined to be contracted with conducting mechanism 21 through actuation of the dial member 5. The threaded aperture of the base 4 has screwed thereinto a binding post 23 which passes through apertureBin support 1 and is, by threaded extension 24, adapted to contact with con- 'ductor 22. and the screw ma be operatively connected with the other-p0 e of the electric generator through conductor 25; Theyconducting mechanism 21 may be apart by a compression spring 29, as clearly shown in Fig; 4 of the-drawing. I

r The outer case BOisscrewed to the vibrator case l' and isprovided with an aperture ;31- through-whichthe graduation of the dial "members 5 and 6 are visible. In orderto actuate the dial-members?) and 6 the former composed. of. two conducting buttons 28'he1d is recessed as at 40 to accommodate a double acting-ratchet wheel'32, carried by bolt 11, and pawls 33 and 34 adapted for coaction therewith, being held in contact with ratchet 32 by means of springs 35. These pawls are arranged to contact with wheel 32 in op 0- site directions and pawl 33 is attached to the upper side of dial'member 5, while pawl 34 is attached to the under side of dial member 6.; Thus, when the bolt is rotated in one direction by handle112, as for instance, in the direction indicated by an arrow in Fig. 2,; then dial member 5 is moved and when ro-J tated in a counter direction, dial member 6; is moved. To prevent movement of the dial member which is not, being actuated by the ratchet, springs 35 are attached to case 30; land press onthe upper face of the dial mem-f r., The operation of the device is as follows a-The person familiar with the par-5 ticular device, that is, with the diSPOSitiOIli of the contacts with respect to the dial} marks, arranges them to engage the contacts and thus completing the circult through bolt 11, washer 13, ring 19, screw 20, conducting mechanism 21, conductor 22 and binding post 23. As disclosed in the drawing, the relative positions of the contacts are such that the combination, with contacts conductively alined, reads 1-3.

I claim I '1. A switch of the character described comprising in combination, a base, a plurality of uxtaposed insulating dial members revoluble with respect thereto, a ring conductor for the uppermost dial member having a lug communicating with the eriphery of said dial member, mechanism carried b the dial member intermediate said uppermost dial and said base, a contact alined to contact with said conducting mechanism of the dial member adjacent said base, when said dial member is in a predetermined position with respect thereto, a binding post operatively connected with said washer, substantially as and for the purpose set forth.

2. In a switch of the character described, the'combination of a base provided with an annular flange, a dial member provided with an annular flange and resting within the said flange of said base, a second dial member resting within the said flange of said'first mentioned dial mem er, said dial members being revoluble with respect to each other and to said base, a bolt passing concentrically through said dial members and said base, a contact exposed to the in ternal periphery of said flange of said base,

riphery of said second bolt, an actuating either'of said dia stantially as and the combination of a base annular flange, a dial mentioned dial'memconductively connected with said means carried by r and members, subfor the purpose set forth. In a switch of the character described provided with an member provided with an annular flange resting within the said flange of said base,

first mentioned dial member, bers ofiher and to said base, a. contact 1: said base, versely throu h mentioned diaI bfitween said buttons to expose thesameat' t spectively, of said flan ing means mentioned and for the purpose set th annular flange, a dial mem an annular flange and resting within the said flange of said base, having a recess, ing within the said a second dial memsaid flange of said said dial memrespect to each e osed to of the said ange of conducting uttons movable transsald flange of said first member, a spring interposed r resting within the being revoluble with e internal periphery periphery, ree, and circuit closat the perip cry of said second dial member, substantially as forth.

4. In a switch of the character described, e combination of a base rovided with an r provided with e internal and externa said dial member a second dial member restflange of the first mentioned dial member, above the said recess th with a revoluble member through the'said dial memb erein, said dial members being revoluble respect to each other and to said base, passing concentrically ers and said base, a contact exposed to the internal perlphery of the said flange of ducting mechanism carried flange of said first mentioned and exposed to the internal and said base, conby the said dial member external periphery thereof, circuit closing means at the periphery of said secon member, a ratchet wheel carried by said revoluble member, and coacting pawls cari ried by said first and said second mentioned dial members, and coacting with said ratchet wheel to actuate the disposed same said ratchet wheel and pawls being hereof,

in the said recess of said first mentioned dial, substantially as and for the purpose set forth.
